you can readily get thin stock which is intended for laminating together
as a multilayer.
I have some 0.5mm, which works basically just the same as 1mm or 1.5mm. I
only use it for very small boards where flexing is not a problem.
Interestingly, thinner material was often used as "flexible" board in
older equipment, like in Fluke 8000 and 8000a meters you will find they
use some thin stock for the display, it is bent 90 degree with maybe 4 or
5 cm radius and works very well.
The thinnest i've ever found was at ebay, it was described as 50um thick
plus 35um copper. I'm not entirely sure about this, since it would require
a rather thin fiberglass mat.
